Our banking & fintech projects

Surf is a company of choice when it comes to mobile banking and trading app development. Check out our recent projects below.

Banking app in only 3 months
We helped а bank develop a mobile app for their VIP customers in three months – a crazy short timeline for a project like that. In addition to banking services, the app offers VIP privileges such as the possibility to book a private helicopter.

One app for 5 different banks
Our Client is a parent company for five commercial banks. They needed an application that would serve completely different types of customers. To solve this challenge, we built a complex design system taking into account the needs of different audiences.

Real-time cryptocurrency trading platform
The Client is a mobile crypto exchange for both casual and professional cryptocurrency investors. Its users monitor price changes, buy, sell, and trade crypto. We made it possible for price quotes to get updated 20 times per second.

Smart banking app on top of legacy backend
We helped the bank rebuild its old app using an improved “smart banking” concept. Because some services had to work using the existing backend, we built a middleware server: a layer that connects the new app to both the old and the new backend.

    Fintech app design

    Finance isn’t as simple as plugging in numbers on a spreadsheet. Financial apps have to be able to display large amounts of data and include complex user flows. Despite the complexity, fintech must make daily financial operations accessible and user-friendly for everyone. And that’s exactly how we design finance apps.

    There was no backend development expertise in our bank, so the work on the server-side fell on different contractors. In the process, we realized that it would be much better to let Surf develop the entire application because they have deep analytics and understanding of our business processes.

    in fintech product development

    If you’re looking for an experienced technical partner to develop a solution for finance, Surf is the right company for you.

    Care about
    your product

    At Surf, you don’t only get technical expertise. We also help you refine your product vision and shape the direction of product design. If you already have a product, we’ll improve conversions by analyzing user behavior and funnels.

    technology stack

    We specialize in both native and cross-platform mobile app development. Our native apps are all written in Swift (for iOS) and Kotlin (for Android) and we use Flutter to develop apps that run on both platforms.
    We have wide experience in working with trading libraries.

    quality control

    If a fintech app has bugs in it, users will think that their financial data is at risk. We have 15 QA engineers on our team with experience testing mobile banking apps. We strictly control your app’s quality at every stage of project development.

    On-time product delivery

    If your time to market is crucial, we can speed up development by building iOS and Android apps simultaneously. We have open code standards, so new developers can jump into a project and get up to speed pretty quickly.
